The square root of a number is a number whose square gives the original number. For example, to find the square root of 36 (which is denoted by √36), we have to think of a number whose square is 36You can remember it this way: When the square moves from one side to the other side of the equation, it becomes the square root.

62 = 36√36 = 6

Thus, the square root of 36 is 6.

A rational number can be expressed as a fraction of integers. We already found that

√36 = 6 = 6/1

So we could express √36 as a fraction of integers and hence it is a rational number.

√36 is a rational number.

We can find the square root of 36 using various methods.

We know that 36 is a perfect square, so we can find its square root using the prime factorization method easily.

### Square Root of 36 Using Prime Factorization

The prime factorization of 36 is as follows:

36 is: 36 = 2 × 2 × 3 × 3

To find the square root of 36, we take one number from each pair of the same numbers and multiply them.

√36 = 2 × 3 = 6

### Square Root of 36 By Long Division

The square root of 36 can be found using the long division as follows.

Think of a number which when multiplied by itself gives

a number that is less than or equal to 36a number that is very close to 36

Since the remainder is 0, we do not need to proceed with long division further and we consider the quotient (which is 6) as the result.

√36 = 6

**Important Notes:**

If we do not have pairs of the same numbers as above, then the prime factorization cannot be used to find the exact square root. Instead, we have to use the long division method.The prime factorization method is used to write a square root of a non-perfect square number in the simplest radical form.

For example: 18 = 2 × 3 × 3 = 2 × 32So, √18 = √2 × √32 = 3√2

## Square Root of 36 Solved Examples

**Example 1**

Jack is instructed to find the square root of 36 using the laws of exponents. Can we help him with this?

**Solution**

The square root can be always replaced with the exponent 1/2.√36 = 36½ = (62)½

Since 62 = 36 = 6 <(am)n = amn>Thus, √36 = 6

**Example 2**

There are as many seats in a minivan as the number of rows in it. If there are 36 seats in it, then how many rows are there?

**Solution**

Let us assume the number of seats in the minivan is y.By the given information,y×y = 36y2 = 36 By taking the square root on both sides,√y2 = √36We know that the square root of y2 is y.Also, we know that 62 = 36 and so the square root of 36 is 6y= 6

The number of rows = 6
